ASTM A135 Steel Pipe yog dab tsi?
ASTM A135 / A135M yog tus qauv kev qhia tshwj xeeb rau hluav taws xob tiv thaiv welded steel yeeb nkab hauv qib A thiab B, npaj rau kev siv tshuab thiab siab thiab rau cov kev pabcuam zoo tib yam rau kev xa cua, dej, chav thiab roj. Cov yeeb nkab yog tsim los ntawm kev tsim cov sawb kauj rau hauv lub tog raj kheej thiab vuam cov seam los ntawm hluav taws xob tsis kam, cov txheej txheem siab - tso tawm uas ua rau nws xaiv kev lag luam rau nruab nrab - kab, nruab nrab - cov kab siab.
Cov kev qhia tshwj xeeb teeb tsa cov tshuaj txwv thiab qhov tsawg kawg nkaus tensile thiab cov khoom yuav tsum tau muaj rau txhua qib, yuav tsum tau hydrostatic los yog tsis yog -kev kuaj hluav taws xob puas tsuaj, thiab suav nrog flattening thiab khoov kuaj ntawm qhov vuam los ua kom pom tias cov seam tau ua kom zoo.
ASTM A795 Steel Pipe yog dab tsi?
ASTM A795 yog tus qauv specification rau dub thiab kub-dipped zinc-coated welded steel yeeb nkab rau kev tiv thaiv hluav taws, nrog rau cov yeeb nkab sprinkler, standpipes thiab lwm yam kev pab cuam xws li condensate ntws kab nyob rau hauv lub network tiv thaiv hluav taws. Cov yeeb nkab yog tsim los ntawm hluav taws xob tiv thaiv vuam lossis hluav taws xob fusion vuam, thiab cov lus qhia tshwj xeeb tau sau nyob ib puag ncig cov kev xav tau ntawm lub neej kev nyab xeeb: kev cia siab kom muaj peev xwm, cov txheej txheem zinc tswj qhov twg cov yeeb nkab galvanized raug xaiv, thiab cov tshuaj txwv tsis pub siv cov welds suab thiab cov yeeb nkab ruaj khov nyob rau hauv ib puag ncig.

Qhov sib txawv ntawm qhov ua tau yog lub hom phiaj. A135 yog qhov dav dav welded yeeb nkab specification, whereas A795 yog sau tshwj xeeb rau cov yeeb nkab tiv thaiv hluav taws thiab suav nrog cov kev cai galvanizing thiab chemistry tswj uas cov neeg tsim qauv tsim thiab cov neeg tsim khoom nyob ntawm qhov sprinkler.
Daim ntawv thov
A135:Tsis tshua muaj thiab nruab nrab siab dej thiab cua kab, irrigation, kua, mechanical piping, laj kab thiab structural raj, thiab cov kev pab cuam dav dav.
A795:ntub dej sprinkler systems, standpipe thiab hose systems, hydrant ceg kab thiab lwm yam hluav taws kev tiv thaiv piping qhov twg galvanized los yog dub yeeb nkab yog ntsia raws li txoj cai hluav taws xob siv.
Ordering, Txheej thiab soj ntsuam sau ntawv
Thaum xaj A795 rau qhov project sprinkler, hais cov txheej txheem kom meej meej: cov yeeb nkab dub, los yog kub -dip galvanized yeeb nkab nrog cov zinc txheej txheej yuav tsum tau nyob rau hauv ib cheeb tsam, thiab paub meej tias qhov txiav xaus, threads los yog grooves yuav tiv thaiv tom qab fabrication. Galvanizing thov ua ntej threading los yog grooving tawm ntawm qhov chaw txiav tawm liab qab, yog li khw- siv zinc- nplua nuj txheej txheej yog feem ntau teev ntawm qhov txiav xaus. Qhov twg cov yeeb nkab yuav tsum tau khoov, xyuas kom meej tias cov galvanized txheej hnyav thiab qib tseem sib haum nrog cov txheej txheem dabtsi yog khoov, thiab xyuas kom meej tias tag nrho cov hydrostatic los yog tsis yog -kev kuaj kev puas tsuaj tau ua tiav ua ntej txheej txheej. Dimensional verification, straightness, thiab tsis muaj teeb meem saum npoo defects xws li laps, seams thiab kab nrib pleb yog lub sij hawm soj ntsuam cov ntsiab lus rau ob qho tib si specifications.
FAQ
Q: ASTM A135 yeeb nkab puas tuaj yeem siv rau hauv cov tshuab tua hluav taws?
Nws tuaj yeem siv rau kev ua haujlwm siab thiab kev siv tshuab, tab sis cov qauv kev tiv thaiv hluav taws yog ib txwm sau ib ncig ntawm cov yeeb nkab rau ASTM A795; txoj cai hluav taws siv tau tswj hwm qhov uas tsim nyog rau qhov muab qhov system.
Q: Dab tsi yog qhov zoo ntawm A795 yeeb nkab?
A795 yog sau tshwj xeeb rau kev pab tiv thaiv hluav taws, npog ob qho tib si dub thiab kub -dip galvanized yeeb nkab nrog cov chav kawm txheej txheej, uas ua rau kev ua raws li cov txheej txheem sprinkler ncaj nraim.
Q: Puas yog A795 yeeb nkab galvanized sab hauv thiab sab nraud?
Qhov kub-dipped zinc txheej siv rau ob qho tib si sab hauv thiab sab nraud ntawm cov yeeb nkab raws li muab, thiab txiav xaus, xov thiab zawj ua tom qab txheej txheej ib txwm tiv thaiv nrog kev pom zoo kho txheej.
Q: Yuav ua li cas yog A135 thiab A795 yeeb nkab welded?
Ob leeg feem ntau yog tsim los ntawm hluav taws xob tsis kam vuam ntawm sawb coil, nrog rau cov weld flattened lossis khoov kuaj kom paub tseeb tseeb; A795 kuj tso cai rau hluav taws xob fusion vuam nrog muab tub lim hlau.
Q: Qhov ntsuas siab npaum li cas A135 yeeb nkab nqa?
Cov kev qhia tshwj xeeb teeb tsa phab ntsa tuab, ntsuas qhov siab thiab lub zog xav tau ntau dua li qhov ntsuas siab ruaj khov, thiab qhov tso cai ua haujlwm siab rau qhov loj thiab lub sijhawm tau tsim los ntawm kev siv cov kav dej lossis kev tiv thaiv hluav taws.
